To all whom it may concern:

Be it known that I, ALVAH L. POWELL, a citizen of the United States, residing at Stockton, in the county of San J oaqu n and State of California, have invented certam new and useful Improvements in Mechanical Movements, of. which the following is a specification.

The mechanical movement which is the subject matter of the present application for patent is designed to increase the speed and amplitude of rectilinear reciprocatory motion, and to this end it consists in a novel combination and arrangement of parts to be described hereinafter and claimed, reference being had to the accompanying drawing in which, Figure 1 is an elevation of the mechanism, and Fig. 2 is an edge view thereof.

In the drawing, 1 denotes a cam which is mounted on a power shaft carrying a power wheel 24 to which latter power may be applied through any suitable means, and from any suitable source, such as steam, manual weight, or any other motive power. The

cam works between two opposite rollers 2 and 2*, respectively, carried by a follower rod 3, whereby the latteris given a recti-- linear reciprocatory motion. The-rod 3 carries a cross head 4 having slots 4 in which are located rollers or pins 6 carried by the face of pinions or gears 5 located'on opposite sides of the cross head, thereby imparting an alternating rotary movement to said pinions. The rollers or pins are located inside the periphery of the pinions. A rack 7 is geared to the pinions 5, and is reciprocated thereby. To this rack is fastened,'by means of a lug 9, a rod 8, which latter carries a cross head 10 operatively connected to gear wheels 11 through rollers or pins 12. The

diameter of the gears 11 is reater than the diameter of the gears 5, so t at an increased greater diameter that the gears 11, so that the motion is again increased. This increase of motion can be carried on indefinitely to accomplish whatever purpose for which it might be desired to use the mechanism.

The last gears 17 are in mesh with a rack 18 which is operatively connected to the machine or other part to 'be operated or driven. I

The drawing shows the connection made with a pump 26. I Fastened to the top of therack 18, be-

hind the same, by means of a pin 20, is a In'operation, the'cam1-reciprocates the rod.3, andthe latter actuates the. gears 5.

The rack 7 transmits the motion to the gears 11 at an increased velocity'due to the increased dlameter of the gears. The motion is next transmitted to the gears'17, and as they are considerably larger than the gears 11, the result is a's till larger movement and greater velocity. This motion is then transmitted through the rack 18, gears 21, 22 and 23 to the gears 5. The parts 19 to 23 are designed to assist in balancing the mechanism and to equalize the leverage. I

At 25 is shown a stand for supporting the mechanism, said stand having suitable bearings and guides for the hereinbefore described parts. a A,

The invention is not limited to two sets of increasing gears,.but the sets maybe increased indefinitely to obtain whatever rate of speed may be required.

I claim:

. 1. A mechanical movement comprising a rack mounted for reciprocatory movement, a gear in mesh with therack'and having a fixed position relative to the rack, a reciprocatory member carrying a slotted cross head, a pin carried by the gear and extending into the slot of the cross head, a. second gear of greater diameter than the first-mentioned I ear ackz and a pin carried by the second gear and extending into the slot of the last-men'- tioned cross head.

2. A mechanical movement comprising a. gear, means for imparting an alternating a slotted cross head carried by the rotary movement to said gear, a rack in mesh with the gear, a second gear operatively connected to the rack for receiving an alternating rotary movement therefrom, and of greater diameter than the first mentioned gear, and a rack in mesh with the second into the slot of the cross head, and a rack in gear and movable independently of the firstmesh with the second gear and movable inmentioned rack. dependently of the first-mentioned rack.

3. A mechanical movement comprising a In testimony whereof I aflix my signa- 5 gear, means for imparting an alternating roture in presence of witnesses.

tary movement to said gear, a rack in mesh ALVAH L. POWELL. with the car, a slotted cross head carried. Witnesses: by the me a gear of greater diameter than CLIFTON M. KIZER, the first-mentioned gear, a pin carried by CHAs. H. YOUNG,

L0 the second-mentioned gear and extending BERTHA M. POWELL.
